That's certainly a better option than an analog approach, but our team was not expecting to have to learn a new skill-set during the build season. I guess my frustration is over the loss of a feature that we weren't expecting to lose. Was it common knowledge? If so then shame on us, certainly. We expected a lot of change resulting from the roboRIO adoption, but we weren't expecting the DS to change significantly in parallel. If anything, we had good reason to believe that it would gain functionality rather than lose features.

An excellent example of this is available with the Teensy 3.1.

It looks like a good example of basic I/O, but I think we'd need to use an interrupt-driven input for an encoder application. Our tick rates will be on the order of 10-100 Hz. We'd also want to represent the tick count in an equivalent way to the Enhanced I/O processed it (signed 32-bit integer, IIRC). Time to start reading, I guess...
